I have a short ruby script to periodically change the screen background
under gnome (Ubuntu Linux). Trace statements in the script show that the
script itself is running. The problem is that the system() call is not
working. Note that I’m running it as myself, not as root. The same
script works perfectly when run in a console.
Here’s the command that isn’t working.
ret = system(“gconftool -t str --set
Please accept that the “new_picture” variable has a good value pointing
to a new background. There are traces in the program that write values
to a trace file that I can examine after the fact. The fact that the
trace file is updated also shows the script is running.
Does anyone know why this command would work from a console, but not
from a cron job?
Thanks in advance
